Referring now to FIG. 1 , an exemplary embodiment of an apparatus 100 for generating a video avatar is illustrated. Apparatus 100 includes a computing device 104. Computing device 104 may include any computing device 104 as described in this disclosure, including without limitation a microcontroller, microprocessor, digital signal processor (DSP) and/or system on a chip (SoC) as described in this disclosure.

Computing device 104 may include a single computing device 104 operating independently or may include two or more computing device 104 operating in concert, in parallel, sequentially or the like; two or more computing devices 104 may be included together in a single computing device 104 or in two or more computing devices 104. Computing device 104 may interface or communicate with one or more additional devices as described below in further detail via a network interface device. Network interface device may be utilized for connecting computing device 104 to one or more of a variety of networks, and one or more devices. Examples of a network interface device include, but are not limited to, a network interface card (e.g., a mobile network interface card, a LAN card), a modem, and any combination thereof. Examples of a network include, but are not limited to, a wide area network (e.g., the Internet, an enterprise network), a local area network (e.g., a network associated with an office, a building, a campus or other relatively small geographic space), a telephone network, a data network associated with a telephone/voice provider (e.g., a mobile communications provider data and/or voice network), a direct connection between two computing devices 104, and any combinations thereof. A network may employ a wired and/or a wireless mode of communication. In general, any network topology may be used. Information (e.g., data, software etc.) may be communicated to and/or from a computer and/or a computing device 104. Computing device 104 may include but is not limited to, for example, a computing device 104 or cluster of computing devices 104 in a first location and a second computing device 104 or cluster of computing devices 104 in a second location. Computing device 104 may include one or more computing devices 104 dedicated to data storage, security, distribution of traffic for load balancing, and the like. Computing device 104 may distribute one or more computing tasks as described below across a plurality of computing devices 104 of computing device 104, which may operate in parallel, in series, redundantly, or in any other manner used for distribution of tasks or memory between computing devices 104. Computing device 104 may be implemented using a “shared nothing” architecture in which data is cached at the worker; in an embodiment, this may enable scalability of apparatus 100 and/or computing device 104.

Still referring to FIG. 1 , computing device 104 may be designed and/or configured to perform any method, method step, or sequence of method steps in any embodiment described in this disclosure, in any order and with any degree of repetition. For instance, computing device 104 may be configured to perform a single step or sequence repeatedly until a desired or commanded outcome is achieved; repetition of a step or a sequence of steps may be performed iteratively and/or recursively using outputs of previous repetitions as inputs to subsequent repetitions, aggregating inputs and/or outputs of repetitions to produce an aggregate result, reduction or decrement of one or more variables such as global variables, and/or division of a larger processing task into a set of iteratively addressed smaller processing tasks. Computing device 104 may perform any step or sequence of steps as described in this disclosure in parallel, such as simultaneously and/or substantially simultaneously performing a step two or more times using two or more parallel threads, processor cores, or the like; division of tasks between parallel threads and/or processes may be performed according to any protocol suitable for division of tasks between iterations. Persons skilled in the art, upon reviewing the entirety of this disclosure, will be aware of various ways in which steps, sequences of steps, processing tasks, and/or data may be subdivided, shared, or otherwise dealt with using iteration, recursion, and/or parallel processing.

Continuing to refer to FIG. 1 , computing device 104 may be designed and configured to receive user data. “User data” is data relating to a user application. User data contains a plurality of user data items. A “user data item” is specific data concerning the user that is extracted from the application. User data items may be, without limitation, the candidate's name, gender, past work experience, social cues, language, location, skills, awards, e-mail address, or any other piece of information given in an application. User data may be retrieved from a user data database 108, which may be implemented in any manner suitable for implementation of a database as described in this disclosure, and/or may be received from user input device 112. “User input device” may include without limitation, a display in communication with computing device 104, where a display may include any display as described herein. User input device 112 may include an additional computing device, such as a mobile device, laptop, desktop, computer, and the like. In an embodiment, user input device 112 may have a touch screen to interact with the user. User may input user data through user input device 112. User data is also received as a function of a user application 116. A “user application” is any document relaying information about the user, such as an application for employment is a standard business document that is prepared with questions deemed relevant by employers. User data 120 may be extracted from user application once user submits it to the computing device. Any of user application 116 and/or user data 120 may be input via user inputs 124 at user device, and/or retrieved from user data database 108. User data may alternatively or additionally be modified to prevent bias, for instance and without limitation as described in U.S. Nonprovisional application Ser. No. 17/582,113, filed on 1/24/2022, and entitled “APPARATUS, SYSTEM, AND METHOD FOR CLASSIFYING AND NEUTRALIZING BIAS IN AN APPLICATION,” the entirety of which is incorporated by reference herein.

Still referring to FIG. 1 , computing device must validate a user's identity as a function of the user data. In order for the user to make a video avatar, the computing device must first confirm if the user data matches to the user the video is being generated for. Validating an identity of the user includes computing device 104 confirming that the user data matches to the user initiating generation of the video avatar. An “identity of the user” is the collection of characteristics, or user data items, that are unique to the user and cannot be duplicated. For example, the user data item of the user's name may be extracted from the user application 116 and must be validated that the user requesting the generation of a video avatar is the same user who submitted user application 116. Validation may be done through the user input device, by the collection of data from a database, or on an immutable sequential listing. An “immutable sequential listing,” as used in this disclosure, is a data structure that places data entries in a fixed sequential arrangement, such as a temporal sequence of entries and/or blocks thereof, where the sequential arrangement, once established, cannot be altered or reordered. An immutable sequential listing may be, include and/or implement an immutable ledger, where data entries that have been posted to the immutable sequential listing cannot be altered; a “blockchain” is a system of recording information in a way that makes it difficult or impossible to change, hack, or cheat the system. Immutable sequential listing and blockchain is further explained herein with reference to FIG. 3 . Verification may also be done through the use of a username and password, or any other type of test to ensure identity. Validating an identity of the user may also include a user validation 128 from the user input device. A “user validation” is a specific input from the user that with affirm the validation of the user's identity. User validation 128 may be the click of a button, word command, password entry, voice command, thumb print, or the like. User validation 128 is a test to ensure identity of the user generating video avatar.

Still referring to FIG. 1 , once user identity is validated, the computing device generates a video avatar as a function of the identity validation and user data. In this disclosure, a “video avatar” is a visual representation of a person for use in digital contexts, such as for a job posting, dating website, social media, or the like. Video avatar 140 may include one or more animation files and/or video clips. Video avatar 140 may include one or more files and/or video clips of user. Video avatar 140 may then be utilized by a user to apply to actual jobs or anything where information about themselves needs to be submitted. Video avatar 140 may be any form of video or visuals that portray user data 120. Video avatar 140 may be a slideshow, video, or physical replication of the user as a function of the user data 120. Video avatar 140 is made of a “plurality of video elements”, which are, as used in this disclosure, diverse types of features from a video avatar such as image features, frame features, sound features, graphical features, and the like. After collecting user data 120, computing device 104 may generate a video avatar 140 using video avatar training data 136 comprising information from a plurality of pre-existing video avatars from a video avatar database 132. Generation of video avatar 140 may include generation thereof using a machine-learning training algorithm and video avatar training data, for instance by training a machine-learning model using avatar training data and a machine-learning algorithm as described in further detail below. Machine learning algorithms may include unsupervised machine learning algorithms such as clustering models, k-means clustering, hierarchical clustering, anomaly detection, local outlier factor, neural networks and the like. Machine-learning may include supervised machine learning algorithms using video avatar training data 136. Machine-learning algorithm may train one or more neural networks such as convolutional and/or deep learning networks and are discussed more herein with reference to FIG. 4 . To generate the video avatar, computing device 104 extracts a plurality of user data items from the user data and generates video avatar using the plurality of user data items.

Still referring to FIG. 1 , computing device 104 may generate a video avatar by querying a multimedia database using user-entered data. In an embodiment, multimedia database may include any data structure for ordered storage and retrieval of data, which may be implemented as a hardware or software module. multimedia database may be implemented, without limitation, as a relational database, a key-value retrieval datastore such as a NOSQL database, or any other format or structure for use as a datastore that a person skilled in the art would recognize as suitable upon review of the entirety of this disclosure. Data entries in a multimedia database may be flagged with or linked to one or more additional elements of information, which may be reflected in data entry cells and/or in linked tables such as tables related by one or more indices in a relational database. Persons skilled in the art, upon reviewing the entirety of this disclosure, will be aware of various ways in which data entries in a multimedia database may reflect categories, cohorts, and/or populations of data consistently with this disclosure.

Still referring to FIG. 1 , multimedia database may be populated with one or more relationships between labels, objects, themes, or the like, as introduced in further detail below, and a video avatar; such relationships may be entered in multimedia database by users, where user entry may include entry by one or more expert users such as psychologists, medical experts, or the like, “crowd-sourced” entry by large numbers of users, which may be aggregated, or the like. Where user entries are aggregated, aggregated results may include comparison of aggregated values to threshold numbers; for instance, a relationship between a given label and a video avatar may be recorded where more than a threshold percentage of user entries have identified the two as linked. Relationships between labels, objects, themes, or the like, as introduced in further detail below, and user data items may alternatively or additionally be entered by computing device from a multimedia classifier as described below; for instance a label may be entered in multimedia database with a video avatar most probably associated therewith as identified by a multimedia classifier.

Alternatively or additionally, and still referring to FIG. 1 , computing device 104 may input user inputs to a multimedia classifier and receive an output classifying user inputs to one or more user data items. Computing device 104 may generate multimedia classifier using a classification algorithm, defined as a processes whereby a computing device 104 derives, from training data, a model known as a “classifier” for sorting inputs into categories or bins of data. Classification may be performed using, without limitation, linear classifiers such as without limitation logistic regression and/or naive Bayes classifiers, nearest neighbor classifiers such as k-nearest neighbors classifiers, support vector machines, least squares support vector machines, fisher's linear discriminant, quadratic classifiers, decision trees, boosted trees, random forest classifiers, learning vector quantization, and/or neural network-based classifiers.

Still referring to FIG. 1 , generating a video avatar includes training, using the plurality of user data items and video avatar training data, a machine-learning model. Training data, as used in this disclosure, is data containing correlations that a machine-learning process may use to model relationships between two or more categories of data elements. For instance, and without limitation, training data may include a plurality of data entries, each entry representing a set of data elements that were recorded, received, and/or generated together; data elements may be correlated by shared existence in a given data entry, by proximity in a given data entry, or the like. Multiple data entries in training data may evince one or more trends in correlations between categories of data elements; for instance, and without limitation, a higher value of a first data element belonging to a first category of data element may tend to correlate to a higher value of a second data element belonging to a second category of data element, indicating a possible proportional or other mathematical relationship linking values belonging to the two categories. Multiple categories of data elements may be related in training data according to various correlations; correlations may indicate causative and/or predictive links between categories of data elements, which may be modeled as relationships such as mathematical relationships by machine-learning processes as described in further detail below. Training data may be formatted and/or organized by categories of data elements, for instance by associating data elements with one or more descriptors corresponding to categories of data elements. As a non-limiting example, training data may include data entered in standardized forms by persons or processes, such that entry of a given data element in a given field in a form may be mapped to one or more descriptors of categories. Elements in training data may be linked to descriptors of categories by tags, tokens, or other data elements; for instance, and without limitation, training data may be provided in fixed-length formats, formats linking positions of data to categories such as comma-separated value (CSV) formats and/or self-describing formats such as extensible markup language (XML), enabling processes or devices to detect categories of data. Generating a video avatar includes training a machine-learning model using video avatar training data. “Video avatar training data” is data collected from a plurality of past, pre-generated video avatars that is currently used to help classify and distinguish user data received to generate the current video avatar.

Alternatively or additionally, and still referring to FIG. 1 , training data may include one or more elements that are not categorized; that is, training data may not be formatted or contain descriptors for some elements of data. Machine-learning algorithms and/or other processes may sort training data according to one or more categorizations using, for instance, natural language processing algorithms, tokenization, detection of correlated values in raw data and the like; categories may be generated using correlation and/or other processing algorithms. As a non-limiting example, in a corpus of text, phrases making up a number “n” of compound words, such as nouns modified by other nouns, may be identified according to a statistically significant prevalence of n-grams containing such words in a particular order; such an n-gram may be categorized as an element of language such as a “word” to be tracked similarly to single words, generating a new category as a result of statistical analysis. Similarly, in a data entry including some textual data, a person's name may be identified by reference to a list, dictionary, or other compendium of terms, permitting ad-hoc categorization by machine-learning algorithms, and/or automated association of data in the data entry with descriptors or into a given format. The ability to categorize data entries automatedly may enable the same training data to be made applicable for two or more distinct machine-learning algorithms as described in further detail below. Training data used by computing device 104 may correlate any input data as described in this disclosure to any output data as described in this disclosure.

Still referring to FIG. 1 , multimedia training data, used herein as training data used to generate multimedia classifier, may include, without limitation, a plurality of data entries, each data entry including one or more themes and/or objects and one or more video avatars represented thereby and/or associated therewith. multimedia training data and/or elements thereof may be entered by users, for instance via graphical user interface forms; as a non-limiting example, each such form may present to a user a geometric form, word, image, or the like, and a user may select a label of a user data item for each such geometric form, word, image, or the like from a list of labels provided to the user and/or may enter one or more words in a text entry element, which may be mapped to labels using language processing as described below. multimedia training data also differs from video avatar training data, explained below.

Still referring to FIG. 1 , computing device 104 may be configured to generate multimedia classifier using a Naïve Bayes classification algorithm. Naïve Bayes classification algorithm generates classifiers by assigning class labels to problem instances, represented as vectors of element values. Class labels are drawn from a finite set. Naïve Bayes classification algorithm may include generating a family of algorithms that assume that the value of a particular element is independent of the value of any other element, given a class variable. Naïve Bayes classification algorithm may be based on Bayes Theorem expressed as P(A/B)=P(B/A) P(A)+P(B), where P(AB) is the probability of hypothesis A given data B also known as posterior probability; P(B/A) is the probability of data B given that the hypothesis A was true; P(A) is the probability of hypothesis A being true regardless of data also known as prior probability of A; and P(B) is the probability of the data regardless of the hypothesis. A naive Bayes algorithm may be generated by first transforming training data into a frequency table. Computing device 104 may then calculate a likelihood table by calculating probabilities of different data entries and classification labels. Computing device 104 may utilize a naive Bayes equation to calculate a posterior probability for each class. A class containing the highest posterior probability is the outcome of prediction. Naïve Bayes classification algorithm may include a gaussian model that follows a normal distribution. Naïve Bayes classification algorithm may include a multinomial model that is used for discrete counts. Naïve Bayes classification algorithm may include a Bernoulli model that may be utilized when vectors are binary.

With continued reference to FIG. 1 , computing device 104 may be configured to generate multimedia classifier using a K-nearest neighbors (KNN) algorithm. A “K-nearest neighbors algorithm” as used in this disclosure, includes a classification method that utilizes feature similarity to analyze how closely out-of-sample-features resemble training data to classify input data to one or more clusters and/or categories of features as represented in training data; this may be performed by representing both training data and input data in vector forms, and using one or more measures of vector similarity to identify classifications within training data, and to determine a classification of input data. K-nearest neighbors algorithm may include specifying a K-value, or a number directing the classifier to select the k most similar entries training data to a given sample, determining the most common classifier of the entries in the database, and classifying the known sample; this may be performed recursively and/or iteratively to generate a classifier that may be used to classify input data as further samples. For instance, an initial set of samples may be performed to cover an initial heuristic and/or “first guess” at an output and/or relationship, which may be seeded, without limitation, using expert input received according to any process as described herein. As a non-limiting example, an initial heuristic may include a ranking of associations between inputs and elements of training data. Heuristic may include selecting some number of highest-ranking associations and/or training data elements.

With continued reference to FIG. 1 , generating k-nearest neighbors algorithm may generate a first vector output containing a data entry cluster, generating a second vector output containing an input data, and calculate the distance between the first vector output and the second vector output using any suitable norm such as cosine similarity, Euclidean distance measurement, or the like. Each vector output may be represented, without limitation, as an n-tuple of values, where n is at least two values. Each value of n-tuple of values may represent a measurement or other quantitative value associated with a given category of data, or attribute, examples of which are provided in further detail below; a vector may be represented, without limitation, in n-dimensional space using an axis per category of value represented in n-tuple of values, such that a vector has a geometric direction characterizing the relative quantities of attributes in the n-tuple as compared to each other. Two vectors may be considered equivalent where their directions, and/or the relative quantities of values within each vector as compared to each other, are the same; thus, as a non-limiting example, a vector represented as [5, 10, 15] may be treated as equivalent, for purposes of this disclosure, as a vector represented as [1, 2, 3]. Vectors may be more similar where their directions are more similar, and more different where their directions are more divergent; however, vector similarity may alternatively or additionally be determined using averages of similarities between like attributes, or any other measure of similarity suitable for any n-tuple of values, or aggregation of numerical similarity measures for the purposes of loss functions as described in further detail below. Any vectors as described herein may be scaled, such that each vector represents each attribute along an equivalent scale of values. Each vector may be “normalized,” or divided by a

“length” attribute, such as a length attribute l as derived using a Pythagorean norm:

${l = \sqrt{{\sum}_{i = 0}^{n}a_{i}^{2}}},$

where a_(i) is attribute number i of the vector. Scaling and/or normalization may function to make vector comparison independent of absolute quantities of attributes, while preserving any dependency on similarity of attributes; this may, for instance, be advantageous where cases represented in training data are represented by different quantities of samples, which may result in proportionally equivalent vectors with divergent values. As a non-limiting example, K-nearest neighbors algorithm may be configured to classify an input vector including a plurality of user-entered words and/or phrases, a plurality of attributes of a user data item, such as spoken or written text, objects depicted in images, metadata, or the like, to clusters representing themes.

Continuing to refer to FIG. 1 , machine-learning algorithms may be implemented using techniques for development of linear regression models. Linear regression models may include ordinary least squares regression, which aims to minimize the square of the difference between predicted outcomes and actual outcomes according to an appropriate norm for measuring such a difference (e.g. a vector-space distance norm); coefficients of the resulting linear equation may be modified to improve minimization. Linear regression models may include ridge regression methods, where the function to be minimized includes the least-squares function plus term multiplying the square of each coefficient by a scalar amount to penalize large coefficients. Linear regression models may include least absolute shrinkage and selection operator (LASSO) models, in which ridge regression is combined with multiplying the least-squares term by a factor of 1 divided by double the number of samples. Linear regression models may include a multi-task lasso model wherein the norm applied in the least-squares term of the lasso model is the Frobenius norm amounting to the square root of the sum of squares of all terms. Linear regression models may include the elastic net model, a multi-task elastic net model, a least angle regression model, a LARS lasso model, an orthogonal matching pursuit model, a Bayesian regression model, a logistic regression model, a stochastic gradient descent model, a perceptron model, a passive aggressive algorithm, a robustness regression model, a Huber regression model, or any other suitable model that may occur to persons skilled in the art upon reviewing the entirety of this disclosure. Linear regression models may be generalized in an embodiment to polynomial regression models, whereby a polynomial equation (e.g. a quadratic, cubic or higher-order equation) providing a best predicted output/actual output fit is sought; similar methods to those described above may be applied to minimize error functions, as will be apparent to persons skilled in the art upon reviewing the entirety of this disclosure,

Still referring to FIG. 1 , machine-learning algorithms may include, without limitation, linear discriminant analysis. Machine-learning algorithm may include quadratic discriminate analysis. Machine-learning algorithms may include kernel ridge regression. Machine-learning algorithms may include support vector machines, including without limitation support vector classification-based regression processes.

Machine-learning algorithms may include nearest neighbors algorithms. Machine-learning algorithms may include Gaussian processes such as Gaussian Process Regression. Machine-learning algorithms may include cross-decomposition algorithms, including partial least squares and/or canonical correlation analysis. Machine-learning algorithms may include naive Bayes methods. Machine-learning algorithms may include algorithms based on decision trees, such as decision tree classification or regression algorithms. Machine-learning algorithms may include ensemble methods such as bagging meta-estimator, forest of randomized tress, AdaBoost, gradient tree boosting, and/or voting classifier methods. Machine-learning algorithms may include neural net algorithms, including convolutional neural net processes.

With continued reference to FIG. 1 , models may be generated using alternative or additional artificial intelligence methods, including without limitation by creating an artificial neural network, such as a convolutional neural network comprising an input layer of nodes, one or more intermediate layers, and an output layer of nodes. Connections between nodes may be created via the process of “training” the network, in which elements from a training dataset are applied to the input nodes, a suitable training algorithm (such as Levenberg-Marquardt, conjugate gradient, simulated annealing, or other algorithms) is then used to adjust the connections and weights between nodes in adjacent layers of the neural network to produce the desired values at the output nodes. This process is sometimes referred to as deep learning. This network may be trained using training data.

Still referring to FIG. 1 , machine-learning algorithms may include supervised machine-learning algorithms. Supervised machine learning algorithms, as defined herein, include algorithms that receive a training set relating a number of inputs to a number of outputs, and seek to find one or more mathematical relations relating inputs to outputs, where each of the one or more mathematical relations is optimal according to some criterion specified to the algorithm using some scoring function. For instance, a supervised machine-learning process may include a scoring function representing a desired form of relationship to be detected between inputs and outputs; scoring function may, for instance, seek to maximize the probability that a given input and/or combination of elements inputs is associated with a given output to minimize the probability that a given input is not associated with a given output. Scoring function may be expressed as a risk function representing an “expected loss” of an algorithm relating inputs to outputs, where loss is computed as an error function representing a degree to which a prediction generated by the relation is incorrect when compared to a given input-output pair provided in training data. Persons skilled in the art, upon reviewing the entirety of this disclosure, will be aware of various possible variations of supervised machine learning algorithms that may be used to determine relation between inputs and outputs. Machine learning model is further described herein with reference to FIG. 4 .

With continued reference to FIG. 1 , supervised machine-learning processes may include classification algorithms, defined as processes whereby a computing device 104 derives, from training data, a model for sorting inputs into categories or bins of data. Classification may be performed using, without limitation, linear classifiers such as without limitation logistic regression and/or naive Bayes classifiers, nearest neighbor classifiers including without limitation k-nearest neighbors classifiers, support vector machines, decision trees, boosted trees, random forest classifiers, and/or neural network-based classifiers.

Still referring to FIG. 1 , machine learning processes may include unsupervised processes. An unsupervised machine-learning process, as used herein, is a process that derives inferences in datasets without regard to labels; as a result, an unsupervised machine-learning process may be free to discover any structure, relationship, and/or correlation provided in the data. Unsupervised processes may not require a response variable; unsupervised processes may be used to find interesting patterns and/or inferences between variables, to determine a degree of correlation between two or more variables, or the like. Unsupervised machine-learning algorithms may include, without limitation, clustering algorithms and/or cluster analysis processes, such as without limitation hierarchical clustering, centroid clustering, distribution clustering, clustering using density models, subspace models, group models, graph-based models, signed graph models, neural models, or the like. Unsupervised learning may be performed by neural networks and/or deep learning protocols as described above.

Continuing to refer to FIG. 1 , machine-learning processes as described in this disclosure may be used to generate machine-learning models. A machine-learning model, as used herein, is a mathematical representation of a relationship between inputs and outputs, as generated using any machine-learning process including without limitation any process as described above, and stored in memory; an input is submitted to a machine-learning model once created, which generates an output based on the relationship that was derived. For instance, and without limitation, a linear regression model, generated using a linear regression algorithm, may compute a linear combination of input data using coefficients derived during machine-learning processes to calculate an output datum. As a further non-limiting example, a machine-learning model may be generated by creating an artificial neural network, such as a convolutional neural network comprising an input layer of nodes, one or more intermediate layers, and an output layer of nodes. Connections between nodes may be created via the process of “training” the network, in which elements from a training dataset are applied to the input nodes, a suitable training algorithm (such as Levenberg-Marquardt, conjugate gradient, simulated annealing, or other algorithms) is then used to adjust the connections and weights between nodes in adjacent layers of the neural network to produce the desired values at the output nodes. This process is sometimes referred to as deep learning.

Still referring to FIG. 1 , computing device 104 may be configured to identify inputs and correlated outputs for video avatar training set 136, which correlated inputs and outputs may be used to train video avatar, using a first feature learning algorithm that inputs video avatar training data 136. For instance, and without limitation, video clips, animations, sound files, or the like corresponding to particular elements of user data may be matched thereto using a feature learning algorithm, which matching may cause such clips to be added to video avatar based thereon. A “feature learning algorithm,” as used herein, is a machine-learning algorithm that identifies associations between elements of data in a training data set, where particular outputs and/or inputs are not specified. For instance, and without limitation, a feature learning algorithm may detect co-occurrences of sets of user data items, as defined above, with each other and with video avatars. Computing device 104 may perform a feature learning algorithm by dividing user data items from a given user into various sub-combinations of such data to create user data sets as described above and evaluate which user data sets tend to co-occur with which other user data sets, and video avatars. In an embodiment, first feature learning algorithm may perform clustering of data; for instance, a number of clusters into which data from training data sets may be sorted using feature learning may be set as a number of video avatars and/or elements thereof such as video clips.

Continuing refer to FIG. 1 , a feature learning and/or clustering algorithm may be implemented, as a non-limiting example, using a k-means clustering algorithm. A “k-means clustering algorithm” as used in this disclosure, includes cluster analysis that partitions n observations or unclassified cluster data entries into k clusters in which each observation or unclassified cluster data entry belongs to the cluster with the nearest mean, using, for instance video avatar training set 136 as described above. “Cluster analysis” as used in this disclosure, includes grouping a set of observations or data entries in way that observations or data entries in the same group or cluster are more similar to each other than to those in other groups or clusters. Cluster analysis may be performed by various cluster models that include connectivity models such as hierarchical clustering, centroid models such as k-means, distribution models such as multivariate normal distribution, density models such as density-based spatial clustering of applications with nose (DBSCAN) and ordering points to identify the clustering structure (OPTICS), subspace models such as biclustering, group models, graph-based models such as a clique, signed graph models, neural models, and the like. Cluster analysis may include hard clustering whereby each observation or unclassified cluster data entry belongs to a cluster or not. Cluster analysis may include soft clustering or fuzzy clustering whereby each observation or unclassified cluster data entry belongs to each cluster to a certain degree such as for example a likelihood of belonging to a cluster; for instance, and without limitation, a fuzzy clustering algorithm may be used to identify clustering of gene combinations with multiple disease states, and multimedia versa. Cluster analysis may include strict partitioning clustering whereby each observation or unclassified cluster data entry belongs to exactly one cluster. Cluster analysis may include strict partitioning clustering with outliers whereby observations or unclassified cluster data entries may belong to no cluster and may be considered outliers. Cluster analysis may include overlapping clustering whereby observations or unclassified cluster data entries may belong to more than one cluster. Cluster analysis may include hierarchical clustering whereby observations or unclassified cluster data entries that belong to a child cluster also belong to a parent cluster.

With continued reference to FIG. 1 , computing device 104 may generate a k-means clustering algorithm receiving unclassified user data items and/or combinations thereof with video avatars as inputs and outputs a definite number of classified data entry cluster wherein the data entry clusters each contain cluster data entries. K-means algorithm may select a specific number of groups or clusters to output, identified by a variable “k.” Generating a k-means clustering algorithm includes assigning inputs containing unclassified data to a “k-group” or “k-cluster” based on feature similarity. Centroids of k-groups or k-clusters may be utilized to generate classified data entry cluster. K-means clustering algorithm may select and/or be provided “k” variable by calculating k-means clustering algorithm for a range of k values and comparing results. K-means clustering algorithm may compare results across different values of k as the mean distance between cluster data entries and cluster centroid. K-means clustering algorithm may calculate mean distance to a centroid as a function of k value, and the location of where the rate of decrease starts to sharply shift, this may be utilized to select a k value. Centroids of k-groups or k-cluster include a collection of feature values which are utilized to classify data entry clusters containing cluster data entries. K-means clustering algorithm may act to classify a given video avatar to one or more user data sets, enabling computing device 104 to identify user data sets correlated with video avatars.

With continued reference to FIG. 1 , generating a k-means clustering algorithm may include generating initial estimates for k centroids which may be randomly generated or randomly selected from unclassified data input. K centroids may be utilized to define one or more clusters. K-means clustering algorithm may assign unclassified data to one or more k-centroids based on the squared Euclidean distance by first performing a data assigned step of unclassified data. K-means clustering algorithm may assign unclassified data to its nearest centroid based on the collection of centroids ci of centroids in set C. Unclassified data may be assigned to a cluster based on

dist(ci, x)², where argmin includes argument of the minimum, ci includes a collection of centroids in a set C, and dist includes standard Euclidean distance. K-means clustering module may then recompute centroids by taking mean of all cluster data entries assigned to a centroid's cluster. This may be calculated based on ci=1/|Si|Σxi

Si^(xi). K-means clustering algorithm may continue to repeat these calculations until a stopping criterion has been satisfied such as when cluster data entries do not change clusters, the sum of the distances have been minimized, and/or some maximum number of iterations has been reached.

Still referring to FIG. 1 , k-means clustering algorithm may be configured to calculate a degree of similarity index value. A “degree of similarity index value” as used in this disclosure, includes a distance measurement indicating a measurement between each data entry cluster generated by k-means clustering algorithm and a selected user data sets and video avatars. Degree of similarity index value may indicate how close a particular combination of video avatars is to being classified by k-means algorithm to a particular cluster. K-means clustering algorithm may evaluate the distances of the combination of video avatars to the k-number of clusters output by k-means clustering algorithm. Short distances between a video avatar and a cluster may indicate a higher degree of similarity between video avatars and a particular cluster. Longer distances between video avatars and a cluster may indicate a lower degree of similarity between video avatars and a particular cluster.

With continued reference to FIG. 1 , k-means clustering algorithm selects a classified data entry cluster as a function of the degree of similarity index value. In an embodiment, k-means clustering algorithm may select a classified data entry cluster with the smallest degree of similarity index value indicating a high degree of similarity between user data sets, video avatars and a particular data entry cluster. Alternatively or additionally k-means clustering algorithm may select a plurality of clusters having low degree of similarity index values to user data sets, video avatars, indicative of greater degrees of similarity. Degree of similarity index values may be compared to a threshold number indicating a minimal degree of relatedness suitable for inclusion of user data sets, video avatars in a cluster, where degree of similarity indices falling under the threshold number may be included as indicative of high degrees of relatedness. The above-described illustration of feature learning using k-means clustering is included for illustrative purposes only and should not be construed as limiting potential implementation of feature learning algorithms; persons skilled in the art, upon reviewing the entirety of this disclosure, will be aware of various additional or alternative feature learning approaches that may be used consistently with this disclosure.

With continued reference to FIG. 1 , video avatar training data 136 may be stored in and/or retrieved from one or more databases; for instance, a video avatar training set may be stored in and/or retrieved from a video avatar training database. Video avatar training database may include any data structure suitable for use as multimedia database as described above. Data entries in a video avatar training database may be flagged with or linked to one or more additional elements of information, which may be reflected in data entry cells and/or in linked tables such as tables related by one or more indices in a relational database. Persons skilled in the art, upon reviewing the entirety of this disclosure, will be aware of various ways in which data entries in a user database may reflect categories of data consistently with this disclosure. Video avatar training database may include one or more tables from which data records may be retrieved with linking data. One or more tables may include a user data item table and a video avatar table, which are further described below with reference to FIG. 2 .

Alternatively or additionally, and still referring to FIG. 1 , video avatar training set and/or data used therefor, including without limitation user data items and/or data describing video avatars, may be stored in a video avatar training database 132, which may be implemented in any way suitable for implementation of a multimedia database as described above.

Referring now to FIG. 2 , an exemplary embodiment 200 of video avatar training database 132 is illustrated. Video avatar training database 132 may be implemented as any data structure suitable for use as clustering database 120 as described above in reference to FIG. 1 . Video avatar training database 132 may store one or more video avatars. One or more tables contained within video avatar training database 132 may include user data items table 204; user data items table 204 may store one or more user data items relating to the user. One or more tables contained within video avatar training database 132 may include video avatar table 208; video avatar table 208 may store one or more user data items obtained from an application.

Referring again to FIG. 1 , computing device 104 is configured to generate, using the machine learning model, a video avatar as a function of the video avatar training data. Video avatar training data comprises a plurality of video elements that are classified with user data items to create the video avatar.

Still referring to FIG. 1 , computing device 104 may be configured to generate a video avatar classifier using video avatar training data. Video avatar classifier inputs user data items and outputs a plurality of video elements associated to the user data item. Video avatar training data 136 may be populated by receiving a plurality of user inputs, for instance via graphical user interface forms; as a non-limiting example, each such form may present to a user at least a user data item and a user may select a label for each such user data item from a list of labels provided to the user and/or may enter one or more words in a text entry element, which may be mapped to labels using language processing as described below; label selected by user may correspond to a user-entered identification of a video element of the user data item. Video avatar classifier may input user data items and output video elements.

Continuing to refer to FIG. 1 , computing device 104 is configured to generate video avatar classifier using a classification algorithm, which may be implemented, without limitation, using any classification algorithm suitable for generating a multimedia classifier as described above. As a non-limiting example, video avatar classifier may use a K-nearest neighbors algorithm that may be configured to classify an input vector including a plurality of attributes of a user data item, such as spoken or written text, objects depicted in images, metadata, etc., to clusters representing themes. Video avatar classifier may alternatively or additionally be created using a naïve-Bayes classification algorithm as described above. Video avatar classifier may enable computing device 104 to identify a single theme represented by the best-matching cluster and/or some number of best-matching clusters, such as the K best matching clusters; in the latter case, matching a theme as described below may include matching any of the K best themes, or the most probable theme may be treated as the main theme and the remaining matching clusters may be treated as identifying themes of secondary importance.

Still referring to FIG. 1 , generating a video avatar also may include using an object classifier. Computing device 104 may modify video avatar training data 136, for instance to replace a user data item with plurality of user data item objects; plurality of user data item objects may be used as attributes of a vector associated with a user data item in video avatar training data 136, for instance for use in KNN or other classification algorithms as described above. Objects of plurality of user data item objects may include, without limitation, objects depicted in images or frames of application, objects described in textual data extracted from images or text, and/or converted from spoken words in application, or the like. In an embodiment, computing device 104 may be configured to extract, from each user data item, a plurality of content elements, such as without limitation geometric forms extracted from images and/or video frames, words or phrases of textual data, or the like. Computing device 104 may be configured to classify each content element of the plurality of content elements to an object of a plurality of user data item objects using an object classifier, where the object classifier may be generated using any classification algorithm as described above. Object classifier may classify words, phrases, and/or geometrical forms to clusters corresponding to labels of objects, enabling a vector representing presence or relative frequency of objects to be created, for instance by populating a vector index corresponding to each of a list of objects with a number indicating presence or absence of an object corresponding to an index and/or a number indicating a number of occurrences of an object corresponding to an index. In the latter case, as a non-limiting example, a higher number may indicate a greater prevalence of a given object in the user data item, which may, as a non-limiting example, cause video avatar classifier to classify user data item to a theme consistent with a higher prevalence of a given object; prevalence and/or relative frequency of an object in user data item may also be used, as described below, to determine a degree to which the object is presented in the user data item for additional processing. In an embodiment, computing device 104 may replace user data item with a plurality of objects as described above in video avatar training data 136; for instance, a separate instance of video avatar training data in which user data items are replaced with plurality of objects may be generated, permitting use thereof in place of the original video avatar training data. Where object classifier is updated, for instance by adding to a list of objects corresponding to clusters and rerunning object classifier to classify to the updated list, user data items stored in memory may be subjected to object classifier again to update each plurality of user data item objects; each of these actions, including without limitation rerunning object classifier to classify to the updated list and/or updating plurality of objects, may be performed by computing device 104. Video avatar classifier may likewise be updated by rerunning classification algorithms on updated video element data.

Still referring to FIG. 1 , object classifier and/or classifiers may be run against one or more sets of object training data, where object training data may include any form of object training data as described above. Object training data may include, without limitation, a plurality of data entries, each data entry including one or more content elements and one or more objects represented thereby. Object training data and/or elements thereof may be entered by users, for instance via graphical user interface forms; as a non-limiting example, each such form may present to a user a geometric form, word, image, or the like, and a user may select a label for each such geometric form, word, image, or the like from a list of labels provided to the user and/or may enter one or more words in a text entry element, which may be mapped to labels using language processing as described below.

Still referring to FIG. 1 , generating a video avatar may include classifying the plurality of content elements to a video avatar using a linguistic object classifier. Computing device 104 may be configured to classify textual elements to objects using a linguistic object classifier; that is, object classifier may include a linguistic object classifier. Textual elements may include words or phrases, as described in further detail below, extracted from textual data such as documents or the like. Textual elements may include other forms of data converted into textual data, such as without limitation textual data converted from audio data using speech-to-text algorithms and/or protocols, textual data extracted from images using optical character recognition (OCR), or the like. Linguistic object classifier may include any classifier described above; linguistic object classifier may generate an output classifying an element of textual data to an object according to any classification algorithm as described above. In an embodiment, computing device 104 may train linguistic object classifier using a linguistic classification training set, which may, as a non-limiting example, include elements of textual data and identifications of one or more objects associated therewith. Linguistic classification training set may, for instance, be populated by user entries of textual data along with corresponding user entries identifying and/labeling objects as described above. Computing device 104 may be configured to extract the plurality of content elements by extracting a plurality of textual elements from a verbal component of the user data item and classify the plurality of textual elements using linguistic object classifier.

Generation of linguistic classification training set, mapping of user entries to object labels, and/or classification of textual objects to labels may alternatively or additionally be performed using a language processing algorithm. As used herein, language processing algorithm may operate to produce a language processing model. Language processing model may include a program automatically generated by language processing algorithm to produce associations between one or more words and/or phrases, including without limitation mathematical associations, between such words. Associations between language elements, where language elements include for purposes herein extracted words and/or object labels, without limitation, mathematical associations, including without limitation statistical correlations between any language element and any other language element and/or language elements. Statistical correlations and/or mathematical associations may include probabilistic formulas or relationships indicating, for instance, a likelihood that a given word and/or phrase indicates a given object label and/or a given additional word and/or phrase. As a further example, statistical correlations and/or mathematical associations may include probabilistic formulas or relationships indicating a positive and/or negative association between at least a word and/or phrase and an object label and/or an additional word.

Still referring to FIG. 1 , language processing algorithm may generate the language processing model by any suitable method, including without limitation a natural language processing classification algorithm; language processing model may include a natural language process classification model that enumerates and/or derives statistical relationships between input term and output terms. Algorithm to generate language processing model may include a stochastic gradient descent algorithm, which may include a method that iteratively optimizes an objective function, such as an objective function representing a statistical estimation of relationships between terms, including relationships between input terms and output terms, in the form of a sum of relationships to be estimated. In an alternative or additional approach, sequential tokens may be modeled as chains, serving as the observations in a Hidden Markov Model (HAM). HMMs as used herein are statistical models with inference algorithms that that may be applied to the models. In such models, a hidden state to be estimated may include an association between at least a word and/or phrase and an object label and/or an additional word. There may be a finite number of labels, words and/or phrases, and/or relationships therebetweem an HMM inference algorithm, such as the forward-backward algorithm or the Viterbi algorithm, may be used to estimate the most likely discrete state given a word or sequence of words. Language processing algorithm may combine two or more approaches. For instance, and without limitation, machine-learning program may use a combination of Naive-Bayes, Stochastic Gradient Descent (SGD), and parameter grid-searching classification techniques; the result may include a classification algorithm that returns ranked associations.

Continuing to refer to FIG. 1 , generating language processing model may include generating a vector space, which may be a collection of vectors, defined as a set of mathematical objects that can be added together under an operation of addition following properties of associativity, commutativity, existence of an identity element, and existence of an inverse element for each vector, and can be multiplied by scalar values under an operation of scalar multiplication compatible with field multiplication, and that has an identity element is distributive with respect to vector addition, and is distributive with respect to field addition. Each vector in an n-dimensional vector space may be represented by an n-tuple of numerical values. Each unique extracted word and/or language element as described above may be represented by a vector of the vector space. In an embodiment, each unique extracted and/or other language element may be represented by a dimension of vector space; as a non-limiting example, each element of a vector may include a number representing an enumeration of co-occurrences of the word and/or language element represented by the vector with another word and/or language element. Vectors may be normalized, scaled according to relative frequencies of appearance and/or file sizes. In an embodiment associating language elements to one another as described above may include computing a degree of vector similarity between a vector representing each language element and a vector representing another language element; vector similarity may be measured according to any norm for proximity and/or similarity of two vectors, including without limitation cosine similarity, which measures the similarity of two vectors by evaluating the cosine of the angle between the vectors, which can be computed using a dot product of the two vectors divided by the lengths of the two vectors. Degree of similarity may include any other geometric measure of distance between vectors.

Still referring to FIG. 1 , language processing algorithm may use a corpus of documents to generate associations between language elements in a language processing algorithm, and computing device 104 may then use such associations to analyze words extracted from one or more documents and determine that the one or more documents indicate a given relationship between at least a word and/or phrase and an object label and/or an additional word. In an embodiment, computing device 104 may perform this analysis using a selected set of significant documents, such as documents identified by one or more users and/or expert users, and/or a generalized body of documents and/or co-occurrence data, which may be compiled by one or more third parties. Documents and/or co-occurrence data may be received by computing device 104 by being uploaded by an expert or other persons using, without limitation, file transfer protocol (FTP) or other suitable methods for transmission and/or upload of documents; alternatively or additionally, where a document is identified by a citation, a uniform resource identifier (URI), uniform resource locator (URL) or other datum permitting unambiguous identification of the document, computing device 104 may automatically obtain the documents, co-occurrence data, or the like by downloading and/or navigating to one or more centralized and/or distributed collections thereof. Computing device 104 may alternatively or additionally receive any language processing model from one or more remote devices or third-party devices and utilize such language processing model as described above.

Now referring to FIG. 3 , an exemplary embodiment of an immutable sequential listing 300 is illustrated. Data elements may be listed in an immutable sequential listing 300; data elements may include any form of data, including textual data, image data, encrypted data, cryptographically hashed data, and the like. Data elements may include, without limitation, one or more at least a digitally signed assertions. In one embodiment, a digitally signed assertion 304 is a collection of textual data signed using a secure proof as described in further detail below; secure proof may include, without limitation, a digital signature as described above. Collection of textual data may contain any textual data, including without limitation American Standard Code for Information Interchange (ASCII), Unicode, or similar computer-encoded textual data, any alphanumeric data, punctuation, diacritical mark, or any character or other marking used in any writing system to convey information, in any form, including any plaintext or cyphertext data; in an embodiment, collection of textual data may be encrypted, or may be a hash of other data, such as a root or node of a Merkle tree or hash tree, or a hash of any other information desired to be recorded in some fashion using a digitally signed assertion 304. In an embodiment, collection of textual data states that the owner of a certain transferable item represented in a digitally signed assertion 304 register is transferring that item to the owner of an address. A digitally signed assertion 304 may be signed by a digital signature created using the private key associated with the owner's public key, as described above.

Still referring to FIG. 3 , a digitally signed assertion 304 may describe a transfer of virtual currency, such as crypto-currency as described below. The virtual currency may be a digital currency. Item of value may be a transfer of trust, for instance represented by a statement vouching for the identity or trustworthiness of the first entity. Item of value may be an interest in a fungible negotiable financial instrument representing ownership in a public or private corporation, a creditor relationship with a governmental body or a corporation, rights to ownership represented by an option, derivative financial instrument, commodity, debt-backed security such as a bond or debenture or other security as described in further detail below. A resource may be a physical machine e.g. a ride share vehicle or any other asset. A digitally signed assertion 304 may describe the transfer of a physical good; for instance, a digitally signed assertion 304 may describe the sale of a product. In some embodiments, a transfer nominally of one item may be used to represent a transfer of another item; for instance, a transfer of virtual currency may be interpreted as representing a transfer of an access right; conversely, where the item nominally transferred is something other than virtual currency, the transfer itself may still be treated as a transfer of virtual currency, having value that depends on many potential factors including the value of the item nominally transferred and the monetary value attendant to having the output of the transfer moved into a particular user's control. The item of value may be associated with a digitally signed assertion 304 by means of an exterior protocol, such as the COLORED COINS created according to protocols developed by The Colored Coins Foundation, the MASTERCOIN protocol developed by the Mastercoin Foundation, or the ETHEREUM platform offered by the Stiftung Ethereum Foundation of Baar, Switzerland, the Thunder protocol developed by Thunder Consensus, or any other protocol.

Still referring to FIG. 3 , in one embodiment, an address is a textual datum identifying the recipient of virtual currency or another item of value in a digitally signed assertion 304. In some embodiments, address is linked to a public key, the corresponding private key of which is owned by the recipient of a digitally signed assertion 304. For instance, address may be the public key. Address may be a representation, such as a hash, of the public key. Address may be linked to the public key in memory of a computing device, for instance via a “wallet shortener” protocol. Where address is linked to a public key, a transferee in a digitally signed assertion 304 may record a subsequent a digitally signed assertion 304 transferring some or all of the value transferred in the first a digitally signed assertion 304 to a new address in the same manner. A digitally signed assertion 304 may contain textual information that is not a transfer of some item of value in addition to, or as an alternative to, such a transfer. For instance, as described in further detail below, a digitally signed assertion 304 may indicate a confidence level associated with a distributed storage node as described in further detail below.

In an embodiment, and still referring to FIG. 3 immutable sequential listing 300 records a series of at least a posted content in a way that preserves the order in which the at least a posted content took place. Temporally sequential listing may be accessible at any of various security settings; for instance, and without limitation, temporally sequential listing may be readable and modifiable publicly, may be publicly readable but writable only by entities and/or devices having access privileges established by password protection, confidence level, or any device authentication procedure or facilities described herein, or may be readable and/or writable only by entities and/or devices having such access privileges. Access privileges may exist in more than one level, including, without limitation, a first access level or community of permitted entities and/or devices having ability to read, and a second access level or community of permitted entities and/or devices having ability to write; first and second community may be overlapping or non-overlapping. In an embodiment, posted content and/or immutable sequential listing 300 may be stored as one or more zero knowledge sets (ZKS), Private Information Retrieval (PIR) structure, or any other structure that allows checking of membership in a set by querying with specific properties. Such database may incorporate protective measures to ensure that malicious actors may not query the database repeatedly in an effort to narrow the members of a set to reveal uniquely identifying information of a given posted content.

Still referring to FIG. 3 , immutable sequential listing 300 may preserve the order in which the at least a posted content took place by listing them in chronological order; alternatively or additionally, immutable sequential listing 300 may organize digitally signed assertions 304 into sub-listings 308 such as “blocks” in a blockchain, which may be themselves collected in a temporally sequential order; digitally signed assertions 304 within a sub-listing 308 may or may not be temporally sequential. The ledger may preserve the order in which at least a posted content took place by listing them in sub-listings 308 and placing the sub-listings 308 in chronological order. The immutable sequential listing 300 may be a distributed, consensus-based ledger, such as those operated according to the protocols promulgated by Ripple Labs, Inc., of San Francisco, Calif., or the Stellar Development Foundation, of San Francisco, Calif, or of Thunder Consensus. In some embodiments, the ledger is a secured ledger; in one embodiment, a secured ledger is a ledger having safeguards against alteration by unauthorized parties. The ledger may be maintained by a proprietor, such as a system administrator on a server, that controls access to the ledger; for instance, the user account controls may allow contributors to the ledger to add at least a posted content to the ledger, but may not allow any users to alter at least a posted content that have been added to the ledger. In some embodiments, ledger is cryptographically secured; in one embodiment, a ledger is cryptographically secured where each link in the chain contains encrypted or hashed information that makes it practically infeasible to alter the ledger without betraying that alteration has taken place, for instance by requiring that an administrator or other party sign new additions to the chain with a digital signature. Immutable sequential listing 300 may be incorporated in, stored in, or incorporate, any suitable data structure, including without limitation any database, datastore, file structure, distributed hash table, directed acyclic graph or the like. In some embodiments, the timestamp of an entry is cryptographically secured and validated via trusted time, either directly on the chain or indirectly by utilizing a separate chain. In one embodiment the validity of timestamp is provided using a time stamping authority as described in the RFC 3161 standard for trusted timestamps, or in the ANSI ASC x9.95 standard. In another embodiment, the trusted time ordering is provided by a group of entities collectively acting as the time stamping authority with a requirement that a threshold number of the group of authorities sign the timestamp.

In some embodiments, and with continued reference to FIG. 3 , immutable sequential listing 300, once formed, may be inalterable by any party, no matter what access rights that party possesses. For instance, immutable sequential listing 300 may include a hash chain, in which data is added during a successive hashing process to ensure non-repudiation. Immutable sequential listing 300 may include a block chain. In one embodiment, a block chain is immutable sequential listing 300 that records one or more new at least a posted content in a data item known as a sub-listing 308 or “block.” An example of a block chain is the BITCOIN block chain used to record BITCOIN transactions and values. Sub-listings 308 may be created in a way that places the sub-listings 308 in chronological order and link each sub-listing 308 to a previous sub-listing 308 in the chronological order so that any computing device may traverse the sub-listings 308 in reverse chronological order to verify any at least a posted content listed in the block chain. Each new sub-listing 308 may be required to contain a cryptographic hash describing the previous sub-listing 308. In some embodiments, the block chain contains a single first sub-listing 308 sometimes known as a “genesis block.”

Still referring to FIG. 3 , the creation of a new sub-listing 308 may be computationally expensive; for instance, the creation of a new sub-listing 308 may be designed by a “proof of work” protocol accepted by all participants in forming the immutable sequential listing 300 to take a powerful set of computing devices a certain period of time to produce. Where one sub-listing 308 takes less time for a given set of computing devices to produce the sub-listing 308 protocol may adjust the algorithm to produce the next sub-listing 308 so that it will require more steps; where one sub-listing 308 takes more time for a given set of computing devices to produce the sub-listing 308 protocol may adjust the algorithm to produce the next sub-listing 308 so that it will require fewer steps. As an example, protocol may require a new sub-listing 308 to contain a cryptographic hash describing its contents; the cryptographic hash may be required to satisfy a mathematical condition, achieved by having the sub-listing 308 contain a number, called a nonce, whose value is determined after the fact by the discovery of the hash that satisfies the mathematical condition. Continuing the example, the protocol may be able to adjust the mathematical condition so that the discovery of the hash describing a sub-listing 308 and satisfying the mathematical condition requires more or less steps, depending on the outcome of the previous hashing attempt. Mathematical condition, as an example, might be that the hash contains a certain number of leading zeros and a hashing algorithm that requires more steps to find a hash containing a greater number of leading zeros, and fewer steps to find a hash containing a lesser number of leading zeros. In some embodiments, production of a new sub-listing 308 according to the protocol is known as “mining.” The creation of a new sub-listing 308 may be designed by a “proof of stake” protocol as will be apparent to those skilled in the art upon reviewing the entirety of this disclosure.

Continuing to refer to FIG. 3 , in some embodiments, protocol also creates an incentive to mine new sub-listings 308. The incentive may be financial; for instance, successfully mining a new sub-listing 308 may result in the person or entity that mines the sub-listing 308 receiving a predetermined amount of currency. The currency may be fiat currency. Currency may be cryptocurrency as defined below. In other embodiments, incentive may be redeemed for particular products or services; the incentive may be a gift certificate with a particular business, for instance. In some embodiments, incentive is sufficiently attractive to cause participants to compete for the incentive by trying to race each other to the creation of sub-listings 308 Each sub-listing 308 created in immutable sequential listing 300 may contain a record or at least a posted content describing one or more addresses that receive an incentive, such as virtual currency, as the result of successfully mining the sub-listing 308.

With continued reference to FIG. 3 , where two entities simultaneously create new sub-listings 308, immutable sequential listing 300 may develop a fork; protocol may determine which of the two alternate branches in the fork is the valid new portion of the immutable sequential listing 300 by evaluating, after a certain amount of time has passed, which branch is longer. “Length” may be measured according to the number of sub-listings 308 in the branch. Length may be measured according to the total computational cost of producing the branch. Protocol may treat only at least a posted content contained the valid branch as valid at least a posted content. When a branch is found invalid according to this protocol, at least a posted content registered in that branch may be recreated in a new sub-listing 308 in the valid branch; the protocol may reject “double spending” at least a posted content that transfer the same virtual currency that another at least a posted content in the valid branch has already transferred. As a result, in some embodiments the creation of fraudulent at least a posted content requires the creation of a longer immutable sequential listing 300 branch by the entity attempting the fraudulent at least a posted content than the branch being produced by the rest of the participants; as long as the entity creating the fraudulent at least a posted content is likely the only one with the incentive to create the branch containing the fraudulent at least a posted content, the computational cost of the creation of that branch may be practically infeasible, guaranteeing the validity of all at least a posted content in the immutable sequential listing 300.

Still referring to FIG. 3 , additional data linked to at least a posted content may be incorporated in sub-listings 308 in the immutable sequential listing 300; for instance, data may be incorporated in one or more fields recognized by block chain protocols that permit a person or computer forming a at least a posted content to insert additional data in the immutable sequential listing 300. In some embodiments, additional data is incorporated in an unspendable at least a posted content field. For instance, the data may be incorporated in an OP RETURN within the BITCOIN block chain. In other embodiments, additional data is incorporated in one signature of a multi-signature at least a posted content. In an embodiment, a multi-signature at least a posted content is at least a posted content to two or more addresses. In some embodiments, the two or more addresses are hashed together to form a single address, which is signed in the digital signature of the at least a posted content. In other embodiments, the two or more addresses are concatenated. In some embodiments, two or more addresses may be combined by a more complicated process, such as the creation of a Merkle tree or the like. In some embodiments, one or more addresses incorporated in the multi-signature at least a posted content are typical crypto-currency addresses, such as addresses linked to public keys as described above, while one or more additional addresses in the multi-signature at least a posted content contain additional data related to the at least a posted content; for instance, the additional data may indicate the purpose of the at least a posted content, aside from an exchange of virtual currency, such as the item for which the virtual currency was exchanged. In some embodiments, additional information may include network statistics for a given node of network, such as a distributed storage node, e.g. the latencies to nearest neighbors in a network graph, the identities or identifying information of neighboring nodes in the network graph, the trust level and/or mechanisms of trust (e.g. certificates of physical encryption keys, certificates of software encryption keys, (in non-limiting example certificates of software encryption may indicate the firmware version, manufacturer, hardware version and the like), certificates from a trusted third party, certificates from a decentralized anonymous authentication procedure, and other information quantifying the trusted status of the distributed storage node) of neighboring nodes in the network graph, IP addresses, GPS coordinates, and other information informing location of the node and/or neighboring nodes, geographically and/or within the network graph. In some embodiments, additional information may include history and/or statistics of neighboring nodes with which the node has interacted. In some embodiments, this additional information may be encoded directly, via a hash, hash tree or other encoding.

With continued reference to FIG. 3 , in some embodiments, virtual currency is traded as a crypto-currency. In one embodiment, a crypto-currency is a digital, currency such as Bitcoins, Peercoins, Namecoins, and Litecoins. Crypto-currency may be a clone of another crypto-currency. The crypto-currency may be an “alt-coin.” Crypto-currency may be decentralized, with no particular entity controlling it; the integrity of the crypto-currency may be maintained by adherence by its participants to established protocols for exchange and for production of new currency, which may be enforced by software implementing the crypto-currency. Crypto-currency may be centralized, with its protocols enforced or hosted by a particular entity. For instance, crypto-currency may be maintained in a centralized ledger, as in the case of the XRP currency of Ripple Labs, Inc., of San Francisco, Calif. In lieu of a centrally controlling authority, such as a national bank, to manage currency values, the number of units of a particular crypto-currency may be limited; the rate at which units of crypto-currency enter the market may be managed by a mutually agreed-upon process, such as creating new units of currency when mathematical puzzles are solved, the degree of difficulty of the puzzles being adjustable to control the rate at which new units enter the market. Mathematical puzzles may be the same as the algorithms used to make productions of sub-listings 308 in a block chain computationally challenging; the incentive for producing sub-listings 308 may include the grant of new crypto-currency to the miners. Quantities of crypto-currency may be exchanged using at least a posted content as described above.

Referring now to FIG. 4 , an exemplary embodiment of a machine-learning module 400 that may perform one or more machine-learning processes as described in this disclosure is illustrated. Machine-learning module may perform determinations, classification, and/or analysis steps, methods, processes, or the like as described in this disclosure using machine learning processes. A “machine learning process,” as used in this disclosure, is a process that automatedly uses training data 404 to generate an algorithm that will be performed by a computing device/module to produce outputs 408 given data provided as inputs 412; this is in contrast to a non-machine learning software program where the commands to be executed are determined in advance by a user and written in a programming language.

Still referring to FIG. 4 , “training data,” as used herein, is data containing correlations that a machine-learning process may use to model relationships between two or more categories of data elements. For instance, and without limitation, training data 404 may include a plurality of data entries, each entry representing a set of data elements that were recorded, received, and/or generated together; data elements may be correlated by shared existence in a given data entry, by proximity in a given data entry, or the like. Multiple data entries in training data 404 may evince one or more trends in correlations between categories of data elements; for instance, and without limitation, a higher value of a first data element belonging to a first category of data element may tend to correlate to a higher value of a second data element belonging to a second category of data element, indicating a possible proportional or other mathematical relationship linking values belonging to the two categories. Multiple categories of data elements may be related in training data 404 according to various correlations; correlations may indicate causative and/or predictive links between categories of data elements, which may be modeled as relationships such as mathematical relationships by machine-learning processes as described in further detail below. Training data 404 may be formatted and/or organized by categories of data elements, for instance by associating data elements with one or more descriptors corresponding to categories of data elements. As a non-limiting example, training data 404 may include data entered in standardized forms by persons or processes, such that entry of a given data element in a given field in a form may be mapped to one or more descriptors of categories. Elements in training data 404 may be linked to descriptors of categories by tags, tokens, or other data elements; for instance, and without limitation, training data 404 may be provided in fixed-length formats, formats linking positions of data to categories such as comma-separated value (CSV) formats and/or self-describing formats such as extensible markup language (XML), JavaScript Object Notation (JSON), or the like, enabling processes or devices to detect categories of data.

Alternatively or additionally, and continuing to refer to FIG. 4 , training data 404 may include one or more elements that are not categorized; that is, training data 404 may not be formatted or contain descriptors for some elements of data. Machine-learning algorithms and/or other processes may sort training data 404 according to one or more categorizations using, for instance, natural language processing algorithms, tokenization, detection of correlated values in raw data and the like; categories may be generated using correlation and/or other processing algorithms. As a non-limiting example, in a corpus of text, phrases making up a number “n” of compound words, such as nouns modified by other nouns, may be identified according to a statistically significant prevalence of n-grams containing such words in a particular order; such an n-gram may be categorized as an element of language such as a “word” to be tracked similarly to single words, generating a new category as a result of statistical analysis. Similarly, in a data entry including some textual data, a person's name may be identified by reference to a list, dictionary, or other compendium of terms, permitting ad-hoc categorization by machine-learning algorithms, and/or automated association of data in the data entry with descriptors or into a given format. The ability to categorize data entries automatedly may enable the same training data 404 to be made applicable for two or more distinct machine-learning algorithms as described in further detail below. Training data 404 used by machine-learning module 400 may correlate any input data as described in this disclosure to any output data as described in this disclosure. As a non-limiting illustrative example, inputs of the current disclosure include user data items, while outputs include video avatars.

Further referring to FIG. 4 , training data may be filtered, sorted, and/or selected using one or more supervised and/or unsupervised machine-learning processes and/or models as described in further detail below; such models may include without limitation a training data classifier 416. Training data classifier 416 may include a “classifier,” which as used in this disclosure is a machine-learning model as defined below, such as a mathematical model, neural net, or program generated by a machine learning algorithm known as a “classification algorithm,” as described in further detail below, that sorts inputs into categories or bins of data, outputting the categories or bins of data and/or labels associated therewith. A classifier may be configured to output at least a datum that labels or otherwise identifies a set of data that are clustered together, found to be close under a distance metric as described below, or the like. Machine-learning module 400 may generate a classifier using a classification algorithm, defined as a processes whereby a computing device and/or any module and/or component operating thereon derives a classifier from training data 404. Classification may be performed using, without limitation, linear classifiers such as without limitation logistic regression and/or naive Bayes classifiers, nearest neighbor classifiers such as k-nearest neighbors classifiers, support vector machines, least squares support vector machines, fisher's linear discriminant, quadratic classifiers, decision trees, boosted trees, random forest classifiers, learning vector quantization, and/or neural network-based classifiers. As a non-limiting example, training data classifier 416 may classify elements of training data to be associated with categories of video avatars.

Still referring to FIG. 4 , machine-learning module 400 may be configured to perform a lazy-learning process 420 and/or protocol, which may alternatively be referred to as a “lazy loading” or “call-when-needed” process and/or protocol, may be a process whereby machine learning is conducted upon receipt of an input to be converted to an output, by combining the input and training set to derive the algorithm to be used to produce the output on demand. For instance, an initial set of simulations may be performed to cover an initial heuristic and/or “first guess” at an output and/or relationship. As a non-limiting example, an initial heuristic may include a ranking of associations between inputs and elements of training data 404. Heuristic may include selecting some number of highest-ranking associations and/or training data 404 elements. Lazy learning may implement any suitable lazy learning algorithm, including without limitation a K-nearest neighbors algorithm, a lazy naïve Bayes algorithm, or the like; persons skilled in the art, upon reviewing the entirety of this disclosure, will be aware of various lazy-learning algorithms that may be applied to generate outputs as described in this disclosure, including without limitation lazy learning applications of machine-learning algorithms as described in further detail below.

Alternatively or additionally, and with continued reference to FIG. 4 , machine-learning processes as described in this disclosure may be used to generate machine-learning models 424. A “machine-learning model,” as used in this disclosure, is a mathematical and/or algorithmic representation of a relationship between inputs and outputs, as generated using any machine-learning process including without limitation any process as described above and stored in memory; an input is submitted to a machine-learning model 424 once created, which generates an output based on the relationship that was derived. For instance, and without limitation, a linear regression model, generated using a linear regression algorithm, may compute a linear combination of input data using coefficients derived during machine-learning processes to calculate an output datum. As a further non-limiting example, a machine-learning model 424 may be generated by creating an artificial neural network, such as a convolutional neural network comprising an input layer of nodes, one or more intermediate layers, and an output layer of nodes. Connections between nodes may be created via the process of “training” the network, in which elements from a training data 404 set are applied to the input nodes, a suitable training algorithm (such as Levenberg-Marquardt, conjugate gradient, simulated annealing, or other algorithms) is then used to adjust the connections and weights between nodes in adjacent layers of the neural network to produce the desired values at the output nodes. This process is sometimes referred to as deep learning.

Still referring to FIG. 4 , machine-learning algorithms may include at least a supervised machine-learning process 428. At least a supervised machine-learning process 428, as defined herein, include algorithms that receive a training set relating a number of inputs to a number of outputs, and seek to find one or more mathematical relations relating inputs to outputs, where each of the one or more mathematical relations is optimal according to some criterion specified to the algorithm using some scoring function. For instance, a supervised learning algorithm may include user data items as described above as inputs, video avatar outputs, and a scoring function representing a desired form of relationship to be detected between inputs and outputs; scoring function may, for instance, seek to maximize the probability that a given input and/or combination of elements inputs is associated with a given output to minimize the probability that a given input is not associated with a given output. Scoring function may be expressed as a risk function representing an “expected loss” of an algorithm relating inputs to outputs, where loss is computed as an error function representing a degree to which a prediction generated by the relation is incorrect when compared to a given input-output pair provided in training data 404. Persons skilled in the art, upon reviewing the entirety of this disclosure, will be aware of various possible variations of at least a supervised machine-learning process 428 that may be used to determine relation between inputs and outputs. Supervised machine-learning processes may include classification algorithms as defined above.

Further referring to FIG. 4 , machine learning processes may include at least an unsupervised machine-learning processes 432. An unsupervised machine-learning process, as used herein, is a process that derives inferences in datasets without regard to labels; as a result, an unsupervised machine-learning process may be free to discover any structure, relationship, and/or correlation provided in the data. Unsupervised processes may not require a response variable; unsupervised processes may be used to find interesting patterns and/or inferences between variables, to determine a degree of correlation between two or more variables, or the like.

Still referring to FIG. 4 , machine-learning module 400 may be designed and configured to create a machine-learning model 424 using techniques for development of linear regression models. Linear regression models may include ordinary least squares regression, which aims to minimize the square of the difference between predicted outcomes and actual outcomes according to an appropriate norm for measuring such a difference (e.g. a vector-space distance norm); coefficients of the resulting linear equation may be modified to improve minimization. Linear regression models may include ridge regression methods, where the function to be minimized includes the least-squares function plus term multiplying the square of each coefficient by a scalar amount to penalize large coefficients. Linear regression models may include least absolute shrinkage and selection operator (LASSO) models, in which ridge regression is combined with multiplying the least-squares term by a factor of 1 divided by double the number of samples. Linear regression models may include a multi-task lasso model wherein the norm applied in the least-squares term of the lasso model is the Frobenius norm amounting to the square root of the sum of squares of all terms. Linear regression models may include the elastic net model, a multi-task elastic net model, a least angle regression model, a LARS lasso model, an orthogonal matching pursuit model, a Bayesian regression model, a logistic regression model, a stochastic gradient descent model, a perceptron model, a passive aggressive algorithm, a robustness regression model, a Huber regression model, or any other suitable model that may occur to persons skilled in the art upon reviewing the entirety of this disclosure. Linear regression models may be generalized in an embodiment to polynomial regression models, whereby a polynomial equation (e.g. a quadratic, cubic or higher-order equation) providing a best predicted output/actual output fit is sought; similar methods to those described above may be applied to minimize error functions, as will be apparent to persons skilled in the art upon reviewing the entirety of this disclosure.
